superchargers? on nitro
#16
There is a valve. It's called the crankshaft. Works just like a rotary valve motor.

well you can force air into anywhere its just a matter of transfering it to where you need it and the pressurized air goes into the crankcase before the combustion chamber which is where it needs to go.

The "supercharger" will destroy your motor. Do not buy one.

what you dont understand is that the supercharger is alot more versatile and tuneable than you think the reason people melt motors is because they dont worry about the driven pulley that spins the turbine. too fast of a turbine=too much boost=MELTDOWN. Too slow of a turbine=not enoughair/fuel=too rich or too lean.
Superchargers and setting them up to work the way they're supposed is all about ratios.

The problem is that you can only mount the band to a specially made fly wheel. The flywheel is a fixed diameter so that a starter box will work.
The reason that superchargers work on real cars is because you can program the fuel injection system to pump more fuel into the motor when the air is being forced in.
It's the nature of the beast. Once glow engines have fuel injection and fuel pumps then it will work.
It would be interesting if there could be a supercharger made that is mounted after the carb. That one will probably work.

I just figured out how you could adjust ratios
The current line of superchargers won't work even if the ratio was set correctly.

ok first of all where did fuel injection come into play with supercharger what happened to i know im going to say it but a supercharger with carbuerators on it. if you look at paxton and vortech superchargers they push THROUGH the carbuerator. not the other way around. i didnt drag race for 4 years to not know what to do to a supercharger to make it work on ANY engine two stroke or not. yeah sometimes you get lucky and you can bolt one on and go but nine times out of ten theres tuning involved just like an engine on first tune up, and it goes beyond just turning idle screws in the carbuerators.

You don't need fuel injection. Carbs have been used with superchargers for a hundred years. If you try to run a lot of boost, the carb can't be richened enough to get the right tune and it leans out. You would probably need to find a HSN from a much bigger motor to get enough fuel into it.
I do agree that having the supercharger between the carb and the motor would work better.

these engines belive it or not are exactly like detroit diesel engines only they run nitro. and detroits are turbocharged and supercharged.
detroit is a motor company that makes tractor trailer engines.
the concept is EXactly the same only smaller and less cylinders. OH and did i mention nitro

Just try it out. Because the superchargers that are sold now won't work on toy cars. Nobody makes different size pulleys to change the boost level. The fuel can't keep up with the air being forced in. The time and money spent would out weigh the benefits.
I would rather get my engine modded to gain performance and run time in the exact way that I wanted.
That is the major downfall of superchargers. If it was able to work on toy cars it would decrease millage too much for racers to care about how much power increased.

How would you get more fuel into the motor with out something to shove more fuel in.
Real cars have fuel pumps are cars use air from the exhaust to push fuel in. As the fuel level drops the pressure in the tank drops causing the motor to run leaner.
If we could come up with something to create more fuel pressure I think it would work.

Have been able to get superchargers for 2strokes for ever. They are called tuned pipes. Do some reading on tuned pipe theory.
Forced induction superchargers dont work well on nitro engines because the timing is controlled by the piston and placement of ports. The exhaust and inlet overlap, so any more volume than what fills the cylinder will just blow out the exhaust.
Detroit diesels whilst twostroke have valves .
